Definitions

  • the present invention relates to a method for propagating Phyllocacti including the steps of providing cuttings from a branch of a mother plant, whereby each cutting is formed by a single phylloclade, providing a sales pot with a growing substrate, the sales pot having a top area, and planting cuttings in the sales pot.
  • Phyllocacti are epiphytic plants, which primarily originate from Central and South America but also for instance from Africa and Madagascar. Of Phyllocacti in production can be mentioned Schlumbergera and Rhipsalidopsis. Schlumbergera and Rhipsalidopsis are native to a small region in the Organ Mountains north of Rio de Janeiro, Brazil in South America. Under natural conditions Schlumbergera truncata will flower in mid to late November and Schlumbergera bridgesii in December thus the common names given are Thanksgiving and Christmas Cacti, respectively.
  • the phylloclades thus form series of connected phylloclades, in the following referred to as branches of phylloclades.
  • EP 0 981 950 B1 discloses a method for propagating Phyllocacti by using cuttings from a mother plant, whereby cuttings are planted in a sales pot with growing substrate in sets of at least two cuttings, and whereby the cuttings of a set are spaced apart over the surface area of said growing substrate in the sales pot.
  • the cuttings may intermediately be planted in multi-compartment trays, in which case each cutting must be planted separately in a compartment so that the cuttings do not stick together when they have to be replanted into the sales pots.
  • the cuttings are allowed to have better space for optimum development as compared to earlier methods, whereby the cuttings of a set were planted very tightly together in the container.
  • the sets comprise two to four cuttings, but preferably the sets comprise three cuttings.
  • the plant must in general have a height of three or four leaves (phylloclades).
  • it has been realised that it may be a drawback of this prior art method that relatively more space is occupied during a relatively longer part of the growing period, whether the cuttings are planted directly in the sales pots or intermediately planted in multi-compartment trays.
  • the object of the present invention is to provide a more efficient method for propagating Phyllocacti.
  • said cuttings are planted directly in the sales pot without intermediate replanting so that a number of cuttings are at least substantially evenly distributed over the growing substrate of the sales pot, said number of cuttings being greater than 0.7 times the square root of the top area of the sales pot when said top area is measured in square centimetres, and the forming of flower buds is initiated when at least substantially all of the cuttings have formed a respective branch having a height corresponding to a predetermined number of new phylloclades extending in direct line on top of each other and placed on top of the respective cutting, said predetermined number of new phylloclades being one when said number of cuttings is less than six, not more than two when said number of cuttings is less than seven, and not more than three when said number of cuttings (2) is less than nine.
  • the number of cuttings planted in a sales pot of a certain size is at least approximately doubled, and the number of new phylloclades extending in direct line on top of each other is generally reduced by one as compared to prior art products. Moreover, the cuttings are planted directly in a sales pot. Because the growth time of one new phylloclade is approximately 7 weeks and because a replanting of cuttings extends the growth time by approximately 3 to 5 weeks, according to the method as defined by the present invention, the production time may be reduced by approximately 10 to 12 weeks.
  • said number of cuttings is greater than 0.75, preferably 0.8, more preferred 0.9, and even more preferred 1.0, times the square root of the top area of the sales pot when said top area is measured in square centimetres.
  • said predetermined number of new phylloclades is not more than two when said number of cuttings is less than eight, and not more than three when said number of cuttings is less than 10.
  • said predetermined number of new phylloclades is not more than two when said number of cuttings is less than ten, and not more than three when said number of cuttings is less than 12.
  • said predetermined number of new phylloclades is generally not more than four or generally not more than five.
  • the sales pot is a standard conical or cylindrical pot having a nominal top diameter approximately from 5 to 7 centimetres, whereby said number of cuttings is at least five, and whereby said predetermined number of new phylloclades is one.
  • the sales pot is a standard conical or cylindrical pot having a nominal top diameter approximately from 7 to 9 centimetres, whereby said number of cuttings is at least eight, and whereby said predetermined number of new phylloclades is two.
  • the sales pot is a standard conical or cylindrical pot having a nominal top diameter approximately from 9 to 11 centimetres, whereby said number of cuttings is at least nine, and whereby said predetermined number of new phylloclades is not more than two.
  • the sales pot is a standard conical or cylindrical pot having a nominal top diameter approximately from 11 to 13 centimetres, whereby said number of cuttings is at least ten, and whereby said predetermined number of new phylloclades is not more than three.
  • the sales pot is a standard conical or cylindrical pot having a nominal top diameter approximately from 13 to 16 centimetres, whereby said number of cuttings is at least 12, and whereby said predetermined number of new phylloclades is not more than four.
  • the top area of the sales pot is generally not more than 200 square centimetres.
  • the Phyllocactus is Schlumbergera and the Phyllocacti planted in the sales pots are subjected to simulated sequential periods of day and night by turning light on and off or at least reducing light substantially, and whereby the forming of flower buds is initiated by reducing the duration of the day periods substantially, such as from approximately between 14 to 15 hours to less than approximately 9 hours.
  • the Phyllocactus is Rhipsalidopsis and whereby the forming of flower buds is initiated by reducing substantially the temperature of the Phyllocacti planted in the sales pots from a temperature of approximately 15 to 25 degrees Celsius to a temperature of approximately 8 to 10 degrees Celsius during a period of approximately 7 to 8 weeks.
  • cuttings are planted in a number of sales pots with said number of cuttings in dependence of the top area of the sales pot and said predetermined number of new phylloclades in dependence of said number of cuttings, and the top area of some of said sales pots is different from the top area of other of said sales pots.
  • the present invention further relates to a potted plant in the form of Phyllocacti planted in a sales pot with a growing substrate, the sales pot having a top area, the Phyllocacti having been propagated by providing cuttings from a branch of a mother plant, each cutting being formed by a single phylloclade, and planting the cuttings in the sales pot.
  • the present invention is characterised in that the cuttings have been planted directly in the sales pot without intermediate replanting so that a number of cuttings are at least substantially evenly distributed over the growing substrate of the sales pot, said number of cuttings being greater than 0.7 times the square root of the top area of the sales pot when said top area is measured in square centimetres, and in that at least substantially all of the cuttings form a respective branch having a height corresponding to a predetermined number of new phylloclades extending in direct line on top of each other and placed on top of the respective cutting, said predetermined number of new phylloclades being one when said number of cuttings is less than five, not more than two when said number of cuttings is less than seven, and generally not more than three.
  • said number of cuttings is greater than 0.75, preferably 0.8, more preferred 0.9, and even more preferred 1.0, times the square root of the top area of the sales pot when said top area is measured in square centimetres.
  • said predetermined number of new phylloclades is not more than two when said number of cuttings is less than ten.
  • the sales pot is a standard conical or cylindrical pot having a nominal top diameter of approximately from 5 to 7 centimetres, said number of cuttings is at least five, and said predetermined number of new phylloclades is one.
  • the sales pot is a standard conical or cylindrical pot having a nominal top diameter of approximately from 7 to 9 centimetres, said number of cuttings is at least eight, and said predetermined number of new phylloclades is two.
  • the sales pot is a standard conical or cylindrical pot having a nominal top diameter of approximately from 9 to 11 centimetres, said number of cuttings is at least nine, and said predetermined number of new phylloclades is not more than two.
  • the sales pot is a standard conical or cylindrical pot having a nominal top diameter of approximately from 11 to 13 centimetres, said number of cuttings is at least ten, and said predetermined number of new phylloclades is not more than three.
  • the sales pot is a standard conical or cylindrical pot having a nominal top diameter approximately from 13 to 16 centimetres, whereby said number of cuttings is at least 12, and whereby said predetermined number of new phylloclades is not more than four.
  • Fig. 1 illustrates a potted plant in the form of Phyllocacti potted according to a prior art method, whereby three cuttings 2 in the form of a single phylloclades (leaves) from a branch of a mother plant have been planted directly without intermediate replanting in a small sales pot 3 with a growing substrate 4.
  • the cuttings 2 have been planted closely together in the centre of the sales pot 3.
  • the sales pot 3 has a nominal diameter of approximately 5 to 6.5 centimetres. It is seen that each cutting 2 has formed a respective branch 6 having a height corresponding to two new phylloclades 7 extending in direct line 8 on top of each other and placed on top of the respective cutting 2.
  • Fig. 4 illustrating a single branch of a Phyllocactus.
  • Fig. 2 illustrates a potted plant in the form of Phyllocacti potted according to a prior art method, whereby three cuttings 2 in the form of a single phylloclades from a branch of a mother plant have been planted in a medium to large sales pot 3 with a growing substrate 4.
  • the cuttings 2 have been planted closely together in the centre of the sales pot 3.
  • the three cuttings 2 have intermediately been planted closely together in one compartment of a multi-compartment tray in order to have better space for optimum development. Subsequently, at a later stage, they have been replanted into the sales pot 3.
  • the sales pot 3 has a nominal diameter of approximately 9 to 10 centimetres.
  • each cutting 2 has formed a respective branch 6 having a height corresponding to three new phylloclades 7 extending in direct line 8 on top of each other and placed on top of the respective cutting 2.

  • the illustrated sales pot 3 has a nominal diameter of approximately 9.5 centimetres corresponding to a top area of 70.9 square centimetres (cm 2 ).
  • the Phyllocacti 1 have been propagated by providing cuttings 2 from a branch of a not shown mother plant, whereby each cutting 2 is formed by a single phylloclade.
  • the cuttings 2 have been planted directly in the sales pot 3 without intermediate replanting so that a number of cuttings 2 are at least substantially evenly distributed over the growing substrate 4 of the sales pot 3. In the illustrated example, said number of cuttings 2 is approximately 10.
  • said number of cuttings 2 is greater than 0.7 times the square root of the top area of the sales pot 3 when said top area is measured in square centimetres. In the present example, it may be calculated that 0.7 times the square root of the top area is 5.9 resulting in a minimum number of cuttings of 6. It is furthermore seen that at least substantially all of the cuttings 2 form a respective branch 6 having a height corresponding to a predetermined number of new phylloclades 7 extending in direct line 8 on top of each other and placed on top of the respective cutting 2. In the illustrated example, said predetermined number of new phylloclades 7 is two. Please also refer to Fig. 4 illustrating a single branch of a Phyllocactus.

  • the sales pot 3 may have any suitable form and dimensions. Apart from the sales pot 3 being conical or cylindrical, it may for instance be square, rectangular etc.
  • a standard sales pot 3 is typically conical in order to facilitate taking a plant out of the pot. Therefore, the top area is typically greater than the bottom area.
  • conical sales pots are given a nominal diameter corresponding approximately to their top diameter.
  • Standard sales pots 3 are available in a number of combinations of diameter and height, depending on the intended use.
  • the growing substrate 4 may be any suitable kind of growing substrate, such as sphagnum, soil, mineral wool, etc. The top surface of the growing substrate 4 typically extends just a little below the top edge of the sales pot 3.
  • the area of the top surface of the growing substrate 4 may for all practical purposes in this context be assumed to be substantially equal to the top area of the sales pot 3.
  • the top area of conical or cylindrical sales pots 3 has been calculated as ⁇ ⁇ r 2 , wherein r is the radius of the top of the pot, set to the half of the nominal diameter.
  • the method for propagating Phyllocacti 1 includes the steps of providing cuttings 2 from a branch of a mother plant, whereby each cutting is formed by a single phylloclade, and providing a sales pot 3 with a growing substrate 4.
  • the cuttings are planted directly in the sales pot 3 without intermediate replanting so that a number of cuttings 2 are at least substantially evenly distributed over the growing substrate 4 of the sales pot 3.
  • said number of cuttings is greater than 0.7 times the square root of the top area of the sales pot 3 when said top area is measured in square centimetres.

  • said number of cuttings 2 is greater than 0.75, preferably 0.8, more preferred 0.9, and even more preferred 1.0, times the square root of the top area of the sales pot 3 when said top area is measured in square centimetres.
  • the sales pot 3 has as mentioned a nominal diameter of approximately 9.5 centimetres corresponding to a top area of 70.9 square centimetres (cm 2 ). It may be calculated that 1.0 times the square root of the top area is 8.4 resulting in a minimum number of cuttings of 9.
